"13a 'citizen of the United States of America, firesiding at Detroit, in the county of Wayne and State of Michigan, have invented certrain new and useful Improvements in Smoke-Consumers, of which the following" a is 'a. specification, reference being ,had

I"? tothe accompanying drawings.

"invention relates to a smoke consu'inec-partieularly designed for furnaces to cfluse' or facilitate the consumption of the a make and gases or products of combustion,

"and thus more perfectly utilize the fuel, while at the same time avoid the many evils the discharge of such products directly into the atmosphere;

V .iThe invention consists, essentially, in an arrangement of air and steam forcing dey which smoke and gasesare re- 'f carried into the fire box or comichaniberof a .boiler furnace, thus permitting of unburnt products of combustion being-consumed to increase the efliciency of a boiler; furnace. .The steam and air ina're farran d so as not to interfere 0 a boiler furnace, the use I o f-flue or other boiler accessories,

1- iaiid evision is made whereby the operation [of t smoke consumer can be easllycontrolled. v j Reference will now vbe had to the drawwherein p 1 is a front elevation of a boller provided with a smoke consuming L apparatus; Fig. 2 is a longitudinal sectional View of a ortion of the same taken on or the ne IIII of Fig 1, looln'ng in ig. 3 is an en- 40 longitudinal sectional view of a'com:

boxes 11 for the branch pipes 12 of a mam steam supply pipe 13 suitably supported in 'front of the boiler setting 1. The inner ends of the branches 12 are provided with elbows 14 and jets 15, said jets extending longitudinally of the nozzles 8 and concentrically thereof to support flared nipples 16 approximately intermediate the ends of the nozzles.- The main steam pipe 13 has a conventional 65 form of valve 17 for controlling thesu ply of steani to the nozzles 8 and the com b tion chamber or fire box 4 of the boiler furnace. Y

The four-way connections 9 are provided with smoke and gas inlet pipes 18 that ex-' tend upwardly in front of the boiler setting l and into the space between the boiler doors- 6 and the flue sheet of the boiler 5, the inner ends of said pipe having funnel or domeand direct smoke and gases from the flues of the boiler 5 into the pi e 18 and into the nozzles 8; the suction pro need by the steam ej-ectors within the nozzles tending to thaw the air, smoke. and gases into the nozzles where the steam, air, smoke and gases thoroughly commingle and are injected into the combustion chamber or fire box 4, wherebyv the unburnt products'of combustion can be consumed. The injection of steam carries the smoke and gases to a point in'proximit to the bridge-wall 2, which serves as a ha e and produces eddies of smoke and gasthat are subjected to the action of the fire upon the grate 3, before escaping to again pass through the flues of the boiler 5 and to a stack or chimney.

To increase the combustion of coal or other fuel within the combustion chamber or fire box,-nozzles 20 are mounted in the boiler setting 1, between the fuel doors 7. These nozzles have three-way connections 21 supporting air intake funnels 22 in longitudinal alinement with the nozzles 20. The three-way connections 21 have detachable caps or stulfing boxes 23 and extendi therethrough are the branches 24 of a bran steam pipe 25 connected-to the main steam supply pipe 13, as best shown in Fig. 1. The branch pipes 24 have the inner ends thereof provided with small three-way connections or Ts 26 su porting jets 27 concentrically of the nozz es 20. The Ts 26 also 7 a support caps 28 and 29 and extending 110 "said caps and longitudinally of the areyalve rods 30. These have xtenio screw threaded 'porfions 31* in screw ed engagementwrththe-czi 528, the outer ends of said VfllVQrhtQg,

In this manner a the combustion chamber is mate? rially-enlivened, the products of combustion thoroughly consumed, and should any prodmet combustion escape a large percentage oifthe sameare collected and returla ed to the v ionchamber for ignition, Itisthrough the medium of the adjustable valves 33that the steam can be shut ofi'to a air and steam injectors, where FjbyjltfiWill be simply drawn into the combn'nlionchamber or fire box 4. With all four lam s in operation, the steam to the same 'canhe controlled by the valve 17. With the w w I shut ofl' there is still a draft from; the v f1 and of'the flue boiler th'rough the' pipes- 18 to the nozzles-8, drawingrin cold 'tity ind both the cold and' hotiair tend to 1 |.m.-. .--'-."combustion in the fire box.'
